Need advice. PA TO FLORIDA?

From Meyersdale, drop down to I 68, go west to I 79 south, go south to the Rt 19 turn to Beckley WV, then take I 77 south, from Meyersdale it is about 7 Hours to Charlotte, NC, plan on going through town during non-rush hours, continue to I 26 east, through Columbia SC, then pick up I 95 south there. right into Savannah. Fill up with fuel at home, then in Wytheville, VA on I 81/ I 77 there are a lot of fuel stops, Flying J and others, the next fuel is right after you cross into SC on I 77, Flying J and others, next place for fuel is around Ridgeland Hardeeville. These are places that usually have lower fuel prices than anywhere and they are fairly easy in/out. Flying J has RV lanes that are usually easy access. I travel this route a LOT.
